JAR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 639,559, dated December 19, 1899.

Application filed August 25, 1899' Serial No. 728,488. (No model.)

in locked position and capable of being oper-' ated by the exercise of a comparatively small amount of exertion and embodying structural features which will reduce the cost of manufacture and afford easy means of application without injury to the jar and which may also be disconnected from one jar and applied to another.

The present device embodies the characteristics of an ordinary bail-fastener without the annoyance incident to the irregularity and impositiveness of such devices and also involves in its operation the salient features of a cam-lock without the disadvantage of the variable pressure exerted by such well-known form of jar-fastening owing to the inability to make them fit all'sorts of jars and because they are not self-adjustable. The present fastener exerts in its operation a contractive force on diametricallyopposed connecting elements carried by the jar and in a plane at right angles to the plane of applied power.

During this operation the present fastener automatically yields while its parts are changing center, and the resultant position of the locking devices is such that it will be impossible for the jar-top toin the least move from its seat or become loose, but adapted when the fastener is entirely released anddisconnected to fully clear the mouth of the jar and form no obstruction whatever to the free removal or outpouring of the contents.

The invention consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a jar-top and a part of a jar, showing the improved fastener applied thereto in locked position. Fig. 2 is an elevation, partially in section, showing the improved fastener applied to the jar and the parts in the position assumed when pressure is first ap plied to arrange them in looking position. Fig. 3 is a detail perspective view of the locking element of the fastener. Fig. 4 is a similar View of a portion of the resistance and supporting elements.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1, as clearly illustrated in Fig. 2, designates a locking element, and 2 a resistance and supporting element, which is clearly shown in detail by Fig. 4. The looking element 1 comprises outwardly directed or inclined yielding coils 3, having the inner terminals continued into an operating-yoke 4 of considerable length and havingits looped extremity 5 made with a pronounced deflection at an angle to the body of the yoke to cause it to assume a close position to the jartop when the fastener is locked and as shown by Fig. 1. The yoke 4 adjacent the innermost coils of the series of coils 3 is divergent and from this widest point gradually converges to a point adjacent the bend made to produce the deflection of the looped extremity 5. The opposite members of the yoke 4 become continuous with the coils 3' at the bases of the latter. The outer terminals of the coils are projected and shaped in the form of contracting arms 6. These arms 6 are inclined upwardly, and the ends are constructed with short bends to provide partial hooks 7. The yoke 4 and arms 6 are on opposing sides of a longitudinal line drawn centrally through the series of coils 3, and the partial hooks 7 have an inward direction. It will be observed that this locking element is formed from a single piece of spring-wire of suitable gage and, as will be more fully hereinafter explained, embodies self-adj ustable features.

The resistance and supporting elements each comprise a semicircular band 8, having one free end formed into a downwardlyturned hook 9, located under the adjacent part of the said band. The opposite extremity is first formed into a loop 10 to form an eye 11 and then extended vertically or in a plane at right angles to the band to form an arm 12, having the upper end provided with a hook 13. Each of these resistance and sup- 2 ceases porting elements are made of spring-wire and are counterparts of each other, and when applied they are reversed, so that the hook 9 of each will be connected to the eye 11 and the arms 12 be disposed at diametrically opposite points on the upper part of the jarbody, and are primarily made long enough to locate the books 13 above the upper surface of the jar-top 14, as clearly shown by Fig. 1. By reversing the elements 2 in the manner stated the hooks 13 will also have their open portions or entrance-throats in opposed position. The method of applying the resistance and supporting elements in connection with the upper part of the jar-body is very simple and can be quickly accomplished, and it will be seen that there is no particular construction of jar-body necessary to accommodate the said resistance and supporting elements.

In assembling the elements of the fastener and after the resistance and supporting ele ments 2 have been applied to the jar-body in the manner set forth the jar-top 14. is placed in position between the arms 12. It is preferred that the jar-top have an upper coneaved seat 15, though this is not actually necessary to the practical working of the fastener, but under ordinary conditions gives the best result and will be explained in connection with the operation of,the fastener. The partial hooks 7 of the arms 6 of the locking element are then caught in the hooks 13 of the arms 12 of the supporting and resistance elements, as clearly shown by Figs. 1 and 2, and a pull is exerted on the loop extremity 5 of the yoke *1 with a downward tendency. By a continuation of this applied operating force the series of coils 3 disposed on opposite sides of the transverse central line through the look ing element will contact with the concaved seat 15 of the top 14. and be first drawn together, as shown by Fig. 2, and slightly pull inwardly on the arms 12 and maintain this position until after the center is passed, when the coils will begin to diverge until they reach their maximum separation, as shown by Fig. 1. During this operation it will be understood that thearms 0 have been turning in the hooks 13; but the downward pressure on the coils and the resistance offered by the arms 12 to a regular overturn of the arms 0 with the series of coils 3 will spring down the said arms 6 and exert a slight torsional twist thereon and produce a strong frictional lock, which will be maintained as long as the series of coils are in diverged positions and in overturned condition when in locked position, as shown by Fig. 1. Owing to the fact that the coils when in locked position have moved past the center and, furthermore, in View of the plurality of frictional contact-points provided by the individual coils accidental disengagement or loosening of the locking element from the position shown by Fig. 1 is completelyiobstrueted and prevented. It will also be observed thatwhen theloekingelement is turned down to a locking position, as well as in opening the same,the fulcrum is continually chang ing, and when the initial locking pressure is exerted on the yoke -1tl1e arms Gare not drawn against the surrounding lip of the jar-mouth or any other part of the jar-body with a crushing and unyielding pressure, and though the said arms 12 may be slightly drawn inward they have a yielding movement of themselves and are permitted to at all times substantially preserve their identity as to position by the resiliency of the coils, which will separate or give, as will be readily apparent. Furthermore, the contact of the series of coils is at opposite points on the jar-top and rounded surfaces contact with the jar-top at said points of bearing, and therefore it will be appreciated that sticking as well as fracture will be prevented. In disconnecting the locking element the partial hooks 7 may be detached from the hooks 13 very quickly and entirely clear the lid or jar-top of any obstruction toits free removal. This will also permit the contents of a jar to be made freely accessible or facilitate the outpouringof the same.

The elements composing the fastener can be made in various sizes, and to suit difierent applications changes in the form, proportions, and minor details ofconstruction might be resorted to without departing from the spirit or nature of the invention.

Having thus described the invention, what is claimedas new is- 1. In a jar-fastener, the combination of resistance and supporting members including upward projections with bent terminals reversely arranged at diametrically opposite points, and a locking elementcomprising opposite arms adapted to be removably connects ed to said projections and having self-adjustable yielding coils between them.

2. In a jar-fastener, the combination of re sistance and supporting elementsincluding upward projections with bent terminals reversely arranged at diametrically opposite points, and a locking element comprising oppositely-extending arms adapted to be removably connected to said projections and having self-adjustable yielding coils between them, connected by an operating pressurereceiving device.

3. In a jar-fastener, the combinationof resistance and supporting elements including projections with bent terminals reversely arranged at diametrically oppositepoints, and a locking element comprising automaticallyadjustable rotatable coilshaving outwardlyextending arms to removably connect with the said projections.

4-. In a jar-fastener, the combination of resistance and supporting elements comprising counterpart members reversely arranged and connected to provide diametrically-disposed projections, and a locking element comprising automatically-adjustable rotatable coils having outwardly-extended and normal upwardly-directed arms to removably connect with the said projections.

5. In a jar-fastener, the combination of resistance and supporting elements including projections at diametrically opposite points, and a locking element comprising automatically-adjustable rotatable coils having outstanding upwardly-extending arms to removably connect with the said projections and an intermediate yoke, the yoke and arms being on opposite sides of a central longitudinal line through the coils.

6. In a jar-fastener, the combination of resistance and supporting elements comprising counterpart members each having an upwardly-extending projection at one end and a locking element at the opposite end, the said members being reversely arranged to dispose the projections at diametrically opposite points, the latter having terminal bends also in reverse position when the parts are assembled, and a locking element having members adapted to engage the said projections.

7. In a jar-fastener, the combination of a supporting element composed of two parts having projections with upper hooked terminals, and a locking element comprising coils with outwardly-projecting arms terminating in partial hooks to engage the said hooked terminals and also provided with an intermediate pressure-receiving yoke having an outer deflected extremity.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
